This is a Watts Radiant HeatWeave mat, a pre arranged open mesh mat containing radiant heating wire. The mat style arrangement allows the wire to be easily laid out on the floor to be heated and set in place with thin-set or self-leveling mortar. The heating wire itself is among the best in the industry, with high grade copper heating elements and insulation that is both corrosion and temperature resistant. The 24002024HW is compatible with Watts Radiant thermostats and electric heating accessories, an array of products designed to improve your electric heating system both during and after installation.

Product Features

Dual High-Grade Copper Heating ElementsThe heating wire's heating element is made from high quality oxygen-free copper, giving the wire uncompromising heat transfer efficiency while retaining flexibility. The entire wire contains a pair of twisted heating elements which keeps the electromagnetic field generated by the wire to a minimum.

ETFE Wire Insulation with Grounding JacketThe heating wire is enveloped in a durable ETFE insulation. This unique insulation offers significant resilience against chemical and temperature corrosion. The two wires are then bound together by a stainless steel jacket for grounding and durability purposes.

Single Power LeadBoth wires connect to the power supply with a single power lead, simplifying labor and reducing installation time.

Flexible Mesh MatThe mat the wires are secured inside of is flexible and is easily cut. This allows you to cut the mat to fit odd shaped areas as well as secure the mat to the underfloor easily with thin-set or self-leveling mortar.

Q: Can this mat be covered with hardwood flooring? What is the best flooring to allow heat transfer through and up?

by Michelle from Michigan on December 30, 2015

A: The Watts Radiant HeatWeave mats can be used with a variety of flooring materials including tile, concrete, stone, laminate, vinyl, hardwood, and even low R-value carpets. Regardless of the flooring materials being used, it is critical to ensure the mat is full encased in a layer of thin set mortar. I would also suggest contacting the manufacturer of the specific flooring material you plan on using as some manufacturers will have specific guidelines or restrictions that must be observed. Vinyl flooring, porcelain tile, and concrete will provide the least resistance to heat transfer.by Chris, Product Expert

Q: Do you need to insulate this with an underlayment or reflective liner on a slab floor?by Susan from Georgia on December 30, 2015

A: When using the Watts Radiant HeatWeave Mats over a concrete slab, it is best practice to use a crack isolation membrane between the slab and mat assembly. This will prevent cracks in the slab from damaging the cable or finish floor and also provide a smaller measure of insulation to direct more of the heat up through the floor rather than down into the slab.by Chris, Product Expert

Q: I wanted to confirm that the mat can be cut into any dimensions, and the wire rerouted as needed?by Dave from Minnesota on December 30, 2015

A: The orange mesh mat can be cut and reoriented as needed to follow the layout of your room. Make sure that if you are removing sections of the mesh entirely, you maintain the appropriate wire spacing. Under no circumstances should you cut the wire itself. Full details regarding fitting the mat to your space can be found in the installation manual.by Chris, Product Expert
